The Gremlin Village Windmill is located in the Gremlin Village in the World of Gremlins. You can activate the windmill by patching the pipes and painting Gus' house as Gus will fix the windmill for you. There are platforms spinning that you can jump on to reach a golden E-Ticket and release the windmill keeper, Gremlin Ditto. He will unlock the secret projector screen you can go through: Clock Cleaners: Part 2.
It is possibly the windmill from the classic cartoon The Old Mill.
